The GOOSYNN Ti-Fi Titanium Fiber Spoke R50 PRO Wheelset offers exceptional vibration dampening and comfort through innovative polymer fiber spokes, though with reduced lateral and torsional stiffness compared to traditional materials.
Pros
- Excellent vibration dampening and comfortable ride
- Lightweight construction
- Wide internal rim width ideal for modern tires
- Titanium ends make spoke replacement easier than traditional polymer spokes
Cons
- Reduced lateral stiffness (27 N/mm vs 56 N/mm for steel)
- Reduced torsional stiffness creating slight power transfer lag
- Potential tire rubbing with tight clearances, especially for heavier riders
- Not ideal for sprinters or very heavy riders due to flex
Key Facts
- Weight: 1,200-1,210g for 50mm deep disc brake wheelset
- 25mm internal rim width
- Polymer fiber spokes with titanium ends offering 52% more elasticity than steel
Reviews & Ratings
The reviewer discusses the GOOSYNN Ti-Fi Titanium Fiber Spoke R50 PRO Wheelset, highlighting its 50mm depth, 25mm internal rim width, and 1,210g weight. He emphasizes the comfort provided by the polymer fiber spokes with titanium ends, which offer 52% more elasticity than steel spokes and reduce vibrations by about 15%, equivalent to an 8 PSI difference in tire pressure. While the wheels are comfortable and smooth over small road imperfections, they have reduced lateral and torsional stiffness, resulting in some flex during hard efforts and a slight lag in power transfer. Real-world testing showed they were the fastest among three wheelsets tested, with no speed penalty despite their comfort advantages. The reviewer notes a recommended weight limit of 85kg due to stiffness concerns, potential clearance issues for heavier riders, the new technology possibly intimidating some bike shops, and a high retail price of $2,299.
AI Summary

The reviewer analyzes the GOOSYNN Ti-Fi Titanium Fiber Spoke R50 PRO Wheelset, focusing on their polymer spokes designed to reduce vibrations while allowing higher tire pressures for lower rolling resistance. He conducts extensive testing comparing them to carbon and steel-spoked wheels, measuring weight, stiffness, vibration dampening, and real-world performance.
AI Summary
Pros
- Lighter weight than carbon and steel spokes (60g lighter than carbon spokes, 321g lighter than steel spokes)
- Better vibration dampening than steel and carbon spokes (15% higher tire pressure possible vs. steel for same ride feel, 20 PSI higher vs. carbon)
- More comfortable ride with reduced road buzz
- Potentially faster due to reduced vibration power losses
- Easy installation compatible with standard carbon-spoke hubs
- Titanium fittings at both ends for durability and compatibility
- May help smooth out pedal stroke by acting like a spring through dead spots
Cons
- Lower lateral stiffness than steel and carbon spokes (27 N/mm vs. 56 N/mm for steel, 41 N/mm for carbon)
- Less torsional stiffness leading to less instant acceleration feel
- Potential for tire rubbing with tight clearances, especially for heavier riders
- Not ideal for sprinters or very heavy riders due to flex
- Some energy loss through constant torsioning/releasing of spokes (though minimal)
- Higher cost likely (implied but not explicitly stated)
Key Points
- Spokes weigh 2.2g each (vs. 2.6g for carbon, 4.1g for steel)
- Ti-Fi stands for Titanium Polymer Fiber
- Wheelset weight: 1,200g (Ti-Fi), 1,261g (carbon), 1,521g (steel comparison)
- 35% more deformation than steel spokes under load
- Tested with Continental GP5000 STR 28mm tires at various pressures
- Real-world testing showed 0.5% faster than steel wheels (within margin of error)
- Compatible with any hub designed for carbon spokes
- 24-spoke version planned for heavier riders/sprinters
